During January 2014 the Met Office promoted a forecast claim of 11-16cm sea level rise by 2030. This failed external review and was replaced by asserting the mistake was omitting to mention the rise was from a 24 year old reference date.

The Met Office changed their text by mentioning 1990 but omitted (at time of writing) to recompute the claimed sea level rise which sensibly must be from today, not 24 years ago.
